6 How it works Kaeser rotary lobe blowers The images depict cross sections of the flow chamber in Kaeser s rotary lobe blower block during the pressure build-up process. Oil-free, isochoric compression process As the intake air passes through the rotary blower s flow chamber, its volume remains constant (isochoric). Actual compression takes place outside the blower block with the accumulation of the air mass taking place in the subsequent process. This adaptive compression always produces only the amount of pressure needed. This makes rotary blowers particularly suitable for applications with a relatively high proportion of idling (e.g. pneumatic conveying) and/or heavily fluctuating pressure. The numbers correspond to the points in the below pressurevolume diagram. 1. Intake of atmospheric air (left rotor). 2. Air is conveyed towards the pressure side; compression begins at the 120 rotation angle due to prior influx of already compressed air. 3. Compression in the flow chamber ceases; discharge begins. 4. Conveyed air mass is discharged into the process. Pressure (P) Thermodynamic Energy Consumption Volume (V) The pressure-volume diagram (P-V diagram) illustrates the energy, or compression work, expended for compression in the blue area between points 1 to 4. 6

7 Kaeser screw blowers Shown here is the pressure build-up process for Kaeser s screw blower block. The air volume is enclosed in the screw chamber. Oil-free isentropic compression process As it is being conveyed through the screw compression block, the entropy of the intake air pressure remains virtually constant (isentropic). Compression takes place in the block, where the air volume is continually reduced until it reaches the discharge and is pushed out against the pressure. The lower compression effort required to achieve the same air volume results in lower energy consumption. Screw blowers are ideally suited for applications with a near constant pressure demand and which require long running periods, such as in filter bed aeration, flotation, etc. The numbers correspond to the points in the below pressurevolume diagram. 1. Intake and capture of atmospheric air. 2. Conveying toward pressure side to outlet. 3. Pressure increase through volume reduction. 4. Compressed air discharged. Pressure (P) Energy Savings Thermodynamic Energy Consumption Volume (V) The pressure-volume diagram (P-V diagram) illustrates the compression work in proportion to the energy expended in the blue area between points 1 to 4. The orange area shows the potential energy savings when a screw blower is used, in comparison to a conventional lobe blower, as long as no overcompression occurs. 7
